3 Claims. (Cl. 4-252) This invention is directed to improvements in plurnbing connections and more particularly to connections adapted to connect a toilet fixture of the so-called wall hung type to a soil pipe line.

The general purpose of the present invention is the provision of a bowl-soil pipe line connection which is devised to serve as a centering means for a carrier or chair whereby the bolt means on the carrier will be aligned or centered with respect to the bolt holes formed in the attaching flange of the bowl or fixture.

A more specic object of the present invention is the provision of a novel coupling for the soil pipeline to wall hung bowls of plumbing fixtures which can be adjusted .to a sealed tight condition in a simple manner.

Other objects of my invention will hereinafter more 'fully appear to those skilled in the art and the essential characteristics thereof are summarized in the claims.

In the drawings Fig. 1 is a side elevation of a so-called "wall hung closet of the syphon jet type with a carrier and lconnection incorporating my invention;

Fig. 2 is an elevational view of part of the carrier member, soil line extension and coupling between carrier,

soil line and bowl xture of the syphon jet type bowl shown in cross section;

Fig. 3 is a rear elevation of the carrier member; and

Fig. 4 is a cross sectional detail of a ca mming surface formed about the perimeter of the main opening for passage of the soil pipe connection and taken substantially along the line 44 of Fig. 3.

For several decades it has been the practice to make a soil pipe connection to a toilet bowl fixture through the use of various mountings which would afford the exertion of pressure on a gasket arranged about the discharge opening or horn of the fixture. yThe art developed to have carriers or chairs which would support the weight of the fixture and the weight of the user while avoiding dependance -upon the building wall to support the fixture free of the floor.

The manufacture of fixtures usually made of vitreous china is an industry separate from the manufacture of the plumbing fittings required to install the fixture with the result that each xture manufacturer produced bowls with bolt openings in the mounting base or fiange of the bowl spaced from the center of the bowl outlet which varied somewhat from the practice of each of the other fixture manufacturers.

The present invention contemplates the provision of a carrier plate and coupling, the carrier plate being provided with median bolt receiving openings which will encompass the locations of the bolt openings of the fixture regardless of the source of manufacture of the fixture where the outlet structure of the xture is centered on the soil pipe connection. This is effected by providing a centering means acting on the soil pipe and carrier to bring about alignment of the median openings of the carrier with the bolt hole openings of the fixture. This is accomplished, in the present instance, by providing a camming surface on the carrier in the form of a conic ICC surface countersunk about the perimeter of the main opening in the carrier, through which the soil pipe coupling to the bowl outlet extends.

A centering sleeve having a conic surface tting the countersink of the carrier is centered upon a ferrule centering on the outlet horn of the fixture and is carried by the sleeve.

Referring to the drawings I show in Fig. l a syphon jet type of bowl or fixture 8 suspended upon pairs of bolts 9 and 10 supporting xture flange 18, the bolts of each pair being equally radially spaced from the centerline of the horn structure 11 of the bowl 8. The bolts are supported on a carrier plate 13 which is universal in its adaptability to support the bolts of a blowout type and a syphon jet type of bowl structures of different manufacturing sources as demonstrated in my copending application Serial Number 619,215, filed October 30, 1956.

The carrier plate 13 has an attached foot structure 14 embedded in the floor structure. Pairs of median openings 15 and median openings 16 formed in the carrier plate, are in shape the composite of all of the openings of bowl xtures obtained from various sources of manufacture of the syphon jet type and which require four suspension bolts.

The centering means whereby the bolt openings 15-16 are brought into alignment with the fixture bolt openings comprises a tapering camming surface 20 formed as a countersink about the perimeter of the main carrier opening 17 into which extends a locking sleeve 21 having a tapered centering flange 22, the tapered or camming surface 2.4 of which aligns the sleeve with the center of the main opening 17 of the carrier when drawn into engagement with the coruntersink or cam surface 20 of the carrier.

The sleeve 21 is externally threaded and a llocking ring 25 is in threaded engagement with the sleeve and when the ring is tightened against the forward face of the carrier, the tapered flange 22 of the sleeve centers the sleeve with the main opening 17 of the carrier.

The centering sleeve has an internal pipe thread 27 to tightly fit the threaded soil pipe nipple 28 and also an internal straight thread 29 for the reception of an adjustable sleeve or ferrule 30. The outer end of the ferrule is provided with a head 31 which fits about the horn structure 11 of the bowl fixture andthe connection compresses the horn gasket 40 when the ferrule and the bolt nuts are adjusted properly. A packing gland 33 is provided with the centering sleeve 21 and the gland by reason of its'disposition serves the purpose of sealing the sleeve and ferrule to the threaded connection.

The manner of use or installation is as follows: the main soil line L and fitting connection 35 with soil pipe extension or nipple 28 are installed before wall W or floor F are completed. The locking or centering sleeve 21 carrying the ferrule 30 are attached to the nipple 28 with the packing gland 33 in place. The chair or carrier plate 13 is placed upon the locking sleeve 21 and locking ring 25 is then placed on the sleeve 21 to draw the carrier plate and sleeve together. The final tightening action of the ring exerting a clamping force axially of the sleeve 21 causes the camming or tapered surface 24 on the sleeve to act upon the camming surface 20 of the carrier to center the sleeve with respect to the carrier bolt openings 15-16 or vice versa to denitely located the bolt openings 15-16 of the carrier with respect to the center of the ferrule 30. Since the head 31 of the ferrule centers about the annular horn structure 11 or outlet structure of the fixture, the carrier median bolt openings 15-16 will always be brought in alignment with the bolt openings in the flange of the fixture irrespective of the dimensionall variations of the iixture bolt hole locations. i

The foot 14 may then be attached by bolts 41 to the carrier bottom region in threaded openings 43 formed in the carrier there being provided two sets of threaded openings 43 at top and bottom regions ofthe carrier in order that the carrier'may be reversed vertically as disclosed in the aforementioned application for the mounting of syphon jet type or blow out type of fixture.

The wall structure W is then finished and floor F is finished after the soil pipe line has been tested and inspected and the ferrule is then adjusted to obtain proper seal with the horn gasket 40 while the ange 18 of the fixture is spaced about one sixteenth ofA an inch from the surface of the finished wall W. Horizontal leveling of a plurality of bowls connected to a common main soil pipe line is obtainedk in a convenient manner in the disclosed arrangement.

While the drawings show the connection'to syphon jet type bowl .the disclosure of the referred' to application shows the manner of adapting the carrier to the support of a blow out type bowl by vertically reversing the carrier plate and by using a single centrally located lower bolt connected to an adjustable stay plate carried by the carrier.
